Fast single-point macromolecular proton fraction (MPF) mapping is a recent magnetic resonance imaging (MRI) method enabling quantitative assessment of myelin content in neural tissues. To date, the reported technical implementations of MPF mapping utilized high-field MRI equipment (1.5 T or higher), … Introduction. Single-point imaging (SPI) is a scan technique in which only one point in k-space is acquired after each excitation. As each point is acquired at a fixed time after the excitation pulse, the effect from relaxation, chemical shifts, field inhomogeneities, diffusion, and other line-broadening mechanisms is constant, and the phase increment between successive encoding steps is This grouping of RRMS patients based on a single time point MRI might support the clinical evaluation of MS patients and contribute to the selection of disease-modifying drugs. However, the prognostic value of the proposed cut-offs for brain atrophy concerning disease progression needs to be evaluated in longitudinal studies.
